Hydroxysodalite (HS) Zeolite membrane was prepared onto seeded mullite supports using a new crystallization method called Dry Gel Conversion Technique. Molar composition of the starting gel of HS zeolite membrane was SiO2/Al2O3=1.0, Na2O/Al2O3=65, and H2O/Al2O3=1000. X-ray diffraction (XRD) patterns of the membranes exhibited peaks corresponding to the support and the zeolite. The crystal species were characterized by XRD and morphology of the supports subjected to crystallization was characterized by Scanning electron microscopy (SEM). Separation performance of HS zeolite membranes was studied for water-Ethanol mixtures using pervaporation (PV). The membranes showed good selectivity towards water in the water-ethanol mixtures. Water permeates faster because of its preferential adsorption into the nano-pores of the hydrophilic zeolite membrane. In PV of water-ethanol mixtures, the membrane exhibits a hydrophilic behavior, with a high selectivity towards water and a good flux. The best flux and separation factor of the membranes were 2.05 kg/m.h and 10000, respectively. In addition, these membranes used for hydrogen separation from CH4 and it showed high selectivity and permeability ratio to zeolite membrane preparated by conventional method.

Performances of zeolite, coconut shell, and zeolite+coconut shell-based water cartridges to minimize contaminants of drinking waters were conducted in the present study. The zeolite stones and coconut shell charcoal were powdered to be ≥ 60 meshes. The powders were packed into a cartridge to provide zeolite, coconut shell, and zeolite+coconut shell (1:2) cartridges, respectively. Well waters allowed to flow through each cartridge for a month. Thereafter, each water filtrate was harvested and analyzed numbers of parameters from four variables included in the quality table of drinking water. The total coliform found in each 100 mL of the well water equaled to 460 MPN (most possible number) while the fecal coli equaled to 150. When the well water flowed through the developing cartridges, the MPN content varied which depended on the cartridge materials qualitative compositions. Total coliform remained in water filtrates of the well waters flowed through the cartridges made of zeolite, coconut charcoal, and their mixture (1:2 by volume) were 38, 240, and 96 MPN, respectively. These developed cartridges, therefore, could remove these total coliform from the well waters by 92, 48, and 79 %, respectively. Overall, the performance of the developed cartridge made of zeolite was highest among those cartridges.

This study aimed to obtain chemical data of mercury from some whitening cream distributed in Palu City. The whitening cream samples consisted of 3 groups (A, B and C), each sample of the group was extracted through wet destructions. The qualitative analysis was with HCl 2.0 M, KI 0.50 N, NaOH 2.0 N reagents, while the quantitative analysis was performed with Atomic Absorption Spectroscopy (AAS). The results of the qualitative analysis indicated that the A sample reacted with NaOH 2.0 N reagent delivered yellow precipitates and C sample with KI 0.50 N reagent delivered red precipitates. Both data indicated that both samples showed positive reaction of Hg (II). However, the B samples did not occur the positive reaction indicating Hg. Based on Indonesian National Agency of Drug and Food Control (BPOM) regulation, (No.HK.03.1.23.07.11.6662 of 2011) related to the requirements of microbe and heavy metals contamination in cosmetics, the Hg (II) concentration in cream should be no more than 1,000.0 μg g. AAS results found in present study demonstrated that A sample holded mercury content over the level required by the BPOM, which it was 4,554.00 μg g. The B and C samples were 47.18 and 780.32 μg g respectively, both samples did not exceed the limits set by the regulation but continuous application might be toxic for body.

Zeolite membranes NaA, ZSM-5, Mordenite, NaX and NaY grown onto seeded mullite supports. Separation performance of zeolite membranes were studied for water-dimethylhydrazine mixtures using pervaporation (PV). The best Flux and separation factor of the membranes were 0.62 kg/m.h and 52000, respectively, for NaA zeolite membrane. Strong electrostatic interaction between ionic sites and water molecules (due to its polar nature) makes the zeolite NaA membrane very hydrophilic. Zeolite NaA membranes are thus well suited for separating liquid-phase mixtures by pervaporation. In this study, experiments were conducted with various unsymmetrical dimethylhydrazine (UDMH) –water mixtures (1–20 wt. %) at 25 C . Total flux for UDMH–water mixtures was found to vary from 0.331 to 0.241 kg/m.h with increasing UDMH concentration from 1 to 20 wt.%. Ionic sites of the NaA zeolite matrix play a very important role in water transport through the membrane. Surface diffusion of water occurs in an activated fashion through these sites. A comparison between experimental flux and calculated flux using Stephan Maxwell (S.M.) correlation was made and a linear trend was found to exist for water flux through the membrane with UDMH concentration.

The purpose of this study was to find out the effect of concentration of soursop (Annona muricata) leaf and soaking time on protein and fat contents and sensory quality of raw chicken meat during storage. This research was conducted in Laboratory of Animal Products Technology, Faculty of Animal Husbandry Nusa Cendana University and Laboratory of Veterinary Public Health, East Nusa Tenggara Province Livestock Services Kupang, Indonesia. The experiment was arranged in completely randomized design in a 4x3 factorial lay out with three replications. The first factor was concentration of soursop leaf in water (C) with four levels: 0, 10, 20, and 30 g/L water. The second factor was soaking time of chicken meat (T) with three levels: 0, 10, and 20 minutes. The quality of chicken meat changes were monitored chemically and organoleptically at hours 12 of storage time. Data collected of protein and fat contents of chicken meat were analyzed using Analysis of Variance and continued with Duncan’s Multiple Range Test, while data of organoleptic properties (color and aroma) characteristics were compared using the Kruskal Wallis Test. It was found that both treatment factors concentration of soursop leaf and soaking time with the interactions had significant effect (P<0.01) on protein and fat content of chicken meat. These results also indicated that color characteristics of chicken meat detected by the descriptive panelist were significantly affected by the both factors concentration of soursop leaf and soaking time (P<0.05), while aroma characteristics were insignificantly affected by the treatments.

The experiment was aimed to investigate the effectiveness of bio-slurry and inorganic fertilizer combination on the performance of two rice varieties. A completely randomized design of factorial pattern was used throughout the experiment. The first factor was the combination of bioslurry and NPK fertilizer that consisted of P0: no added fertilizer, P1: NPK fertilizer only, 550 kg/ha; P2: bio-slurry 2.3 tons/ha + NPK fertilizer 400 kg/ha; P3: bio-slurry 4.6 tons/ha + NPK fertilizer 250 kg/ha; P4: bio-slurry 6.9 tons/ha + NPK fertilizer 100 kg/ha; and P5: bio-slurry only, 8.5 tons/ha. Treatments were applied based on nitrogen recommended doses of rice, 165 kg N/ha. The second factor was rice varieties that consisted of V1: IR-64 and V2: Ciherang. Each treatment was repeated three times. Parameters observed were plant height, number of tillers, weight of 1,000 grains, and rice production. Data were statistically analyzed using ANOVA and followed by Duncan’s Multiple Range Test. On the basis of the experimental results it was concluded that bio-slurry may replace the role of inorganic fertilizer in rice production, especially IR64 and Ciherang varieties.

The intrinsic factors that caused aging are enzymes such as hyaluronidase and elastase by oxidative stress mechanism. Antioxidants are the bioactive compounds which are highly important to fight against oxidative stress that can cause aging. Modified compounds o121–15f apigenin have reported can act as an antioxidant. The aim of this study was to determine candidate of apigenin derivative compounds that were potential to inhibit hyaluronidase and elastase enzyme by using molecular docking method with human target protein with pdb.id : 2JIE and 5JMY. Molecular docking was done using windows operating system with several softwares, i.e: PLANTS, YASARA and MarVinSketch. Visualization of bonding modes between the ligand and amino acid residues was done with PyMol. Of the 50 apigenin derivative compounds tested, obtained 9 compounds with lower docking scores than apigenin in inhibiting hyaluronidase and 5 compounds in inhibiting elastase enzyme. 3’6-diamineapigenin had the lowest docking score (-62.39) in inhibiting hyaluronidase enzyme (2JIE) and 3’amineapigenin had the lowest docking score (-91.31) in inhibiting elastase enzyme (5JMY). The binding interactions of the actively docked conformations of the ligand and the target protein have been identified and showed the most amino acid residues that considered affect hyaluronidase and elastase inhibition process such as VAL_710, GLU_762 and VAL_763. Based on these results, there are some antioxidants of the apigenin derivative compounds that recommended as an anti-aging agent. Keywords: apigenin, antioxidant, anti-aging, molecular docking
